FRANK BATTER, OF ST. JOHNS, OREGON.

PORTABLE Foo'r AND BODY WARMIER.

To all whom it may concern:

Be it known that I, FRANK BATTER, a citizen of the United States, andresident of St. Johns, in the county of Multnomah and State of Oregon,have invented a new and. useful Improvement in Portable Foot and Bod rWarmers, of which the following is a specification, reference being hadto the accompanying drawings as constituting a part thereof.

This invention relates to devices which are designed to be worn on theperson as a means for artificially warming the body, head and feet, soas to enable the person to better stand exposure to cold weather.

To this end, my invention comprises the contrivances, combination andfeatures hereinafter described and illustrated in the drawings.

the two circulation tubes connecting a valve bulb with the fluid heaterand the pad placed under the foot, so as to join the two tubes side byside; Fig. 14 isa detail, partly in section, of the helmetpart of mydevice; and Fig. 15 is a sectional detail illustrating the constructionof the casing of the lamp chamber of my device.

The numerals designate the parts referred to.

In its general arrangement, my device comprises a lamp-chamber 1,provided with straps 2, whereby it is adapted to be fastened to thewaist of the person, as shown in Fig. 1.

3 is a helmet under which the user wears a skull cap 4. The lamp-chamber1 is pro into the helmet 3, which in its construction is designed toserve as a flue or discharge for the vitiated air of the lamp-chamber.

1n the upper part ofthe lamp-chamber 1 is removably supported afluid-heater 9, to which are attached two pairs of tubes 10 10 11 11connecting at their extremities with a hollow pad 12, to be placed underthe hollow of each foot. One of each pair of tubes is provided with apump-bulb 13, and the whole being arranged to circulate the fluid heatedin the heater 9, through the foot-pad 12. For convenience, each pair ofsaid fluid-circulating tubes is arranged alongside of one of the legs ofthe wearer, and the pump-bulbs 13 are mounted on pads 13 adapted to beaffixed on the inner side of the legs near the knees by bands 13. Theoutlet air tubes 7, -8, are respectively provided near their upper endswith a hollowdisk 14, shown in plan section and cross section in Figs. 6and 7, and comprising substantially an inner shell 14, having an outercovering of cloth or like fabric 14", and the whole being arranged to beadjusted over the ears of the wearer. Thus the heat of the lamp servesto warm the body, the airoutlet-tubes 7, 8, to supply warmth to theface, and the fluid heater 9, and its connections including the pads 12,to warm the lower extremities of the wearer.

The details of my device in other respects are as follows:

The helmet 3 is constructed of a metal body 3 provided with neck-shield3 and a rim 3. The top is covered by a cover 3,

leaving air escape apertures 3 I Near the top of the helmet is provideda perforated partition 3 and the body walls 8, are provided withperforations 3 Within'the helinet is provided an inner inclined wall 3,serving to prevent any air blowing in through holes 3 down into the lampwith such force as to extinguish the same. To the helmet is removablyfastened a short cloak 15, to be arranged over the shoulders,approximately as shown in Fig. 1, for the purpose of retaining the heatradiated by the outlet tubes 7, 8, about the face. The helmet is securedin place by bands 3.

The lamp-chamber 1 comprises a threepart skiircasing, as illustrated inFig. 15; namely, an inner metal skin 1*, an intermediate sheeting ofasbestos 1 and an outer sheeting of metal 1. The intermediate and theouter sheetings are respectively made with registering holes 1 and theexterior is provided with vertical guides 1, in which is slidably held aslide 1, which when drawn down uncovers the holes 1 and allows part ofthe hot air ofrthe lamp-chamber to radiate through said holes; andsupposingthe wearer to have on an overcoat or cloak, saidradiated heatserves to warm the body.-

When the heat of the lamp-chamber is not to be so utilized, the slide 1may be adjusted to cover the holes 1.

Entering the bottom of the lamp and extending upward is an air-inlettube 1 to which is attached the flexible air-tube 5, above referred to.In the lower part of the lamp chamber is a perforated false bottom 1 todiffuse more evenly the stream of cold fresh air entering through thetube 1.

The lamp 1 is removably secured in place by spring arms 1 engaging withlugs 1 and the top of the lamp is conveniently made with aflange 1,fitting within the open bottom of the lamp-chamber.

The inner sheet 1 of the lamp casing has no perforations so as toprevent smoke being blown out.

In the upper part of the interior of the lamp casingare providedbrackets 1 and 1 The bracket 1 is provided with a stop 1", and thebracket 1' supports a chamber 1, open at both ends and adapted toreceive the fluid-heater 9, which when inserted rests by its inner endon the bracket 1 and is sto ped in'its proper place by stop 1". Theuidheater 9 is provided with inlet and-outlet necks 9 9", to which thetubes 10 10, 11 11, are fastened.

In order to provide for the circulation of an ample volume of fluidthrough the heater 9, over as great a surface of heated metal aspractical, the fluid-heater 9 is preferably made of the constructionshown in Figs. 4:, 4 4". It comprises substantially two parts .9, 9 eachmade with a worm-like duct 9 state? 9, through the necks 9*,respectively; the two partsare separated by a partition 9 the wholebeing rigidly fastened together by rivets 9*, or other correspondinglyconvenient means.

Since the inner end of the fluid-heater 9 will be exposed to the flameof the lamp, and become more or less soiled by reason of a deposit ofsoot thereon, I provide a sheath 9, made with a hinge part 9 and whenthe fluid heater is removed from the lamp-chamber, the sheath 9 is movedover the blackened inner end -soas to drop the hinge part 9 and preventthe soiling of the hands or pockets when carrying the fluid heaterabout.

The tubes 10, 10 11, 11 connecting the heater with the foot pads 12, arepreferably arranged as illustrated in Figs. 10, 12, '13. That is to say,Ifound it convenient to inclose both of said tubes" within a commonouter casing 10", made of cloth, wrapped around the same, substantiallas shown in the cross section Fig. 13, to old the tubes side by side.-The pump bulbs 13 I found convenient to make of metal like a circularbox, the top 13 of which has concentric circular flutings so as to bespringy; and I have provided an auxiliary coil spring 13 to insure thatthe top will retain'the required resiliency to' obtain the pump effectby merely pressing in said top and'then allowing the same to spring backto its normalstate. Each of the pump-bulbs-13 is fastened to a pad 13,provided with a socket 13", the pad being made of rubber, and the objectof the construction described being to render the whole convenient to beaflixed to the legs of the wearer by band 13. I have found it convenientto arrange the pump bulbs o posite to each other near the knee so thatth 9 through the pads 12,' as often as desired, by simp y pressingthereon with the knee. Each of-the pumps 13 is supposed to be provided.with suitable valves for con-' trolling the ingress and e ress of thecirculating fluid; the details of which valves are not shown, being wellknown.

Each of the pads 12 comprises a base 12*, in the center of which issecured an S-tube 12* made of metal or hard rubber, to the ends of whichare aflixed the ends of the circulation tubes (10, 10 esg.) coiled onthe base as shown in Fig. 5. The coiled tubing is provided to preventthe ends of the rubbertubes becoming kinked.

The upper end of the lamp chamber 1 is contracted to a discharge neck oroutlet 1 adapted to receive a piece of the flexible tubing 16 to connecttherewith a duplex outlet valve 16, a detail of which is shown in Fig.8. Such valve 16, comprises a body ey may be operated, to cause acirculation'of heated fluid from the heater .isheld in place by bands12. The S-tube provided in the upper part with necks 16 and 16constituting duplex outlets, and below with an outlet neck 16, on whichis atfixed the upper end of the tubing 16 On the upper-necks 16 areatfixed the lower ends of the outlet tubes 7, 8, and in the body .part16 is journaled transversely a short shaft 16, provided with a'wing 16;and exterior of the valve casing, the shaft 16 is made with a turnbutton 16 see Fig. 1, so that the wing 16 may be arranged to one side orthe other, for the purpose of causing the discharging heated air toascend through the tube 7 or the tube 8; and thereby enabling the wearerof my apparatus to cause the heated air to ascend over thatportion ofthe face which is exposed to'the greatest cold.

To prevent the tubes 7 8, being collapsed and thereby retarding theescape of vitiated air discharged from the lamp, Iprefer to use for suchtubes, tubing provided with an inner spiral wire or rib 17, asillustrated in Fig. 9.
